Biggest Tire We Can Fit On An Rx350/400h?

[NeoN]

Hey just wanted to see whats the biggest tire we can shove under our fenders. 255/45/20? I was wondering about a 265/45/20 or possibly a 274/45/20. Anyone think a 265/275 would rub? would it stick out past the fenders?

Any feedback would be greatly appreciated.

The rear tires' inside sidewall clearance is the limiting factor.

And yes, I speak from experience.

what do you mean? you've got 255/50/18s right? Rey claims his 255/55/18's don't rub at all, without spacers!

My 255/55/18 tires do not rub on my RX. I doubt 255/50/18 will fit without a rear spacer.

Your post doesn't make sense.  If 255/55/18's fit then 255/50/18's will definitely fit.  They are the same width, just slightly shorter in diameter than the 55's.
